Graphic Overlay Plus Dynamic Content Switching - AWS Elemental Live

This is version 2.18 of the AWS Elemental Live documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Live and AWS Elemental Statmux Documentation.

Graphic Overlay Plus Dynamic Content Switching

You can combine the Graphic Overlay feature with the Dynamic Content Switching feature. You can use the Dynamic Content Switching feature to continually add and modify inputs in an event that is running. As you add inputs, you can insert static or motion overlays, as desired. For information on dynamic content switching, see Dynamic Content Switching.

Scheduling Inputs and Overlays

The scheduling of the inputs and the overlays is completely decoupled.

A given input X may be added several times to the dynamic playlist, for example, so that it plays at 2:00 p.m. and then plays again at 3:10 p.m.

If you want an overlay to appear the first time input X plays, you might set its start time for 2:10 p.m. The next time that input X plays, there is no logic to play the same overlay again because 2:10 p.m. has passed. Therefore, if you want the overlay to appear again on input X, you must send a Modify Overlay call again.

Behavior with Different Insertion Options for Static Overlays

Points to remember when using Static Graphic Overlay with Dynamic Content Switching:

  1. Playlist input plus overlay at the input stage.

    The overlay is specified in the Input section of the event. Therefore, however many times you include this input in the playlist, the overlay will be included unless you action to remove it.

    • If you want to include the overlay in a given repetition of the input, you may need to change the start time of the overlay. See the information on the Start Time in the table under Step B: Initial Setup.

    • If you do not want to include the overlay in a given repetition of that input, you must use the REST interface to enter a Modify Static Overlay command and delete the overlay. See Static Graphic Overlay Commands.

  2. Playlist input plus overlay at the global processing stage.

    The scheduling of the inputs and the overlays is completely decoupled.

    A given input X may be added several times to the dynamic playlist, for example, so that it plays at 2:00 p.m. and then plays again at 3:10 p.m.

    If you want an overlay to appear the first time input X plays, you might set its start time for 2:10 p.m. The next time that input X plays, there is no logic to play the same overlay again because 2:10 p.m. has passed.

    Therefore, if you want the overlay to appear again on input X, you must enter the Modify Static Overlay command again.

  3. Playlist input plus overlay at the output stage. The same comments as for global processing stage apply.
